Infinity Sigma/Epsilon wood trim

Hi DIY'ers,
I have a pair of the aforementioned Infnity cabs with the wooden trim around the outside edge of the front and at the bottom and I'd like to sand them down a bit and give them a nice matte finish instead of the current high gloss lacquer (which has it's marks). Does anyone know if it's solid wood or just veneer over particle board, or MDF?
I'd prefer not to find out it's veneer after sanding them down.
